RVideo

Real-time video server for embedded apps. ## What is RVideo RVideo is a library which solves the problem of streaming video from embedded computer-vision applications. Many of such are headless and do not require a dedicated interface, however it is often useful (especially for developers) to see what is happening on the device. RVideo provides a simple API to stream video from your embedded application to a remote client. ## How does it work Unlike other streaming solutions, the goal of RVideo is to provide a minimal overhead for an embedded application it is included into: * Frames are always sent as-is, usually in RAW formats (it is more than enough for most debugging use-cases) * All frames, not received by a client in time, are dropped * No any buffering is performed on the server side * Real-time-safe code is used to minimize the impact on the main application ## Clients RVideo streams can be received with clients provided by crate. For ready-to-use UI, see the [`rvideo-view`](https://crates.io/crates/rvideo-view) crate. ## Locking safety By default, the server uses [parking_lot](https://crates.io/crates/parking_lot) for locking. For real-time applications, the following features are available: * `locking-rt` - use [parking_lot_rt](https://crates.io/crates/parking_lot_rt) crate which is a spin-free fork of parking_lot. * `locking-rt-safe` - use [rtsc](https://crates.io/crates/rtsc) priority-inheritance locking, which is not affected by priority inversion (Linux only). Note: to switch locking policy, disable the crate default features. ## About RVideo is a part of [RoboPLC](https://www.roboplc.com/) project.
